Abstract
The utility model discloses a portable energy-saving DVD player which comprises an operation control circuit, an AC adaptor and a DC battery; the output ends of the AC adaptor and the DC battery are connected with a power supply selecting circuit; the output end of the power supply selecting circuit is connected with a DTV module through a power supply switch circuit; and the operation control circuit is connected with the power supply switch circuit. When the DVD module works, the operation control circuit outputs control signal, and the power supply switch circuit leads the DTV module to be in power-off condition; when the DTV module needs to work, the operation control circuit outputs a control signal, and the power supply switch circuit leads the DTV module to be the on position and controls an LCD to display the video signal of the DTV module at the same time. The energy saving portable DVD player prevents electricity waste when the DTV module is electrified and stands by, thereby reducing electricity consumption.
Description
Technical field:
The utility model relates to a kind of Portable DVD player, especially a kind of energy-saving Portable DVD player that reduces electric energy loss.
Background technology:
Portable DVD player is little with its volume, light weight, extremely consumer's favor of advantage such as easy to carry.The signal receiving circuit (button, remote controller signal receiving circuit etc.) that existing Portable DVD player all is provided with DVD module, DTV module, SD card module, AUX (outside input) module, LCD, loudspeaker, operation control circuit and joins with operation control circuit.Be provided with the AC adapter, the dc-battery that join with AC power simultaneously, be connected to charging control circuit between the output of AC adapter and the dc-battery.The output of AC adapter, dc-battery selects circuit and each module to join by the power supply supply, for each module provides operating voltage.After the start, the voltage that the power supply supply selects circuit to select battery or AC adapter to be provided, because the user can only see and use a module at one time, all the other modules all are in the waiting status that powers on.When the user carried out " mode switch " by panel button or telepilot, operation control circuit promptly received switching signal and exports LCD output control chip to, control it and switch between different inputs, thereby the vision signal of output corresponding module is to LCD.With regard to existing that module is used and the bigger DTV module of waste of energy phenomenon, especially energy consumption that all the other modules power on and wait for, the waste of energy phenomenon is more serious like this.
Summary of the invention:
The utility model is in order to solve existing in prior technology waste of energy phenomenon, a kind of energy-saving Portable DVD player that reduces electric energy loss to be provided.
Technical solution of the present utility model is: a kind of energy-saving Portable DVD player, be provided with operation control circuit, AC adapter, dc-battery, the output of AC adapter, dc-battery and power supply supply select circuit to join, described power supply supply selects the output of circuit to join by power switch circuit and DTV module, and described operation control circuit and power switch circuit join.
The utility model is to select to be connected between circuit and the DTV module power switch circuit of being controlled by operation control circuit in the power supply supply, when the DVD module is worked, operation control circuit output control signal makes the DTV module be in off-position by power switch circuit; When needs DTV module was worked, operation control circuit was promptly exported control signal, makes the DTV module be in "on" position by power switch circuit, controlled the vision signal that LCD shows the DTV module simultaneously.Avoid because of the DTV module because of the waste of energy phenomenon that the standby that powers on produces, can reduce electric energy loss.
Description of drawings:
Fig. 1 is the schematic block circuit diagram in the utility model is implemented.
Embodiment:
Below in conjunction with description of drawings embodiment of the present utility model.As shown in Figure 1: the utility model is the same with prior art, be provided with operation control circuit, AC adapter, charging control circuit, dc-battery, the output of AC adapter, dc-battery and power supply supply select circuit to join, different is that the power supply supply selects the output of circuit to join by power switch circuit and DTV module with prior art, and operation control circuit and power switch circuit join.Power switch circuit quantity can be decided as required, and its structure can be integrated circuit (power conversion chip), also can be made of discrete component, as elements such as triode, resistance, relays.When the DVD module was worked, operation control circuit was to the power switch circuit input low level, and power switch circuit ends, and the operating voltage of DTV module is not provided, and made the DTV module be in off-position; And when mode switch, promptly to the power switch circuit input high level, the power switch circuit conducting provides the operating voltage of DTV module, makes the DTV module in running order after the operation control circuit received signal; Reach the purpose that reduces electric energy loss.
